SAFETY INFORMATION
WARNING
Be sure to clear weapon before starting inspection.
If cover is opened on a fiot cartridge (hot ban-el), an open-cover cookoff could occur and result in
serious Injury or death. Evacuate area for 1 5 minutes and then do IMMEDIATE ACTION. Refer to
page 2-35.
Never reload a runaway machine gun until it has been repaired. Be sure machine gun is cleared
before moving it.
When removing a stuck unfired cartridge, stay clear of the muzzle. Do not allow cartridge to
contact any hard surface. Cartridge may fire on contact. Remove a stuck unfired cartridge using
the same procedures for removing a stuck or ruptured cartridge case.
Before field stripping check that the bolt is in forward position.
Bolt assembly is under spring tension; it can twist and injure your hand.
Barrels issued for a specific gun will not be changed from gun to gun. Each ban-el and bolt
assembly should be tagged during cleaning with the serial number of the receiver (gun) and
should remain together as initially assigned. Interchanging ban-els may result in injury or death.
Insert the hinge pin from one side and the hinge pin latch from the opposite side.
After unloading dummy round, be sure the barrel Is cleared.
Ammunition to be used in machine gun is authorized in Chapter 5.
SAFETY INFORMATION (CONT)
WARNING
Keep weapon pointed at target - down range/impact area.
Keep safety on S until you're ready to fire.
Always check the chamber/bore after clearing the weapon.
Checl( barrel bore and chamber before firing.
Do not interchange bolt assemblies or components from one weapon to another. This may cause
injury or death to personnel.
Change f|ot barrels with your heat protective mitten only or by holding bipod legs. (Refer to page
3-5 for additional hot barrel procedures.)
Do not interchange leaf springs from one model weapon to another.
Check that assigned and spare barrels have been headspaced and tagged to your receiver
Rotate usage of the ban-els. »» 7
Firing Blank Cartridges
Do not fire blank ammunition toward personnel within 20 feet of the muzzle. Fragments of a ckjsure
wad or particles of unbumed propellant might inflict injury within that range.

PREPARING A RANGE CARD
In a defensive situation, make a range card. The essential elements of the range card are:
1 A known Reference Point (RP).
2 The direction and distance from the RP to the machine gun.
3 The machine gun position.
4A The sector of fire with left and right limits (in this case, also Final Protective Line, FPL).
4B Secondary sector.
5 The MAGnetic AZimuth (MAG AZ) of the FPL.
6 Dead space in the FPL where there is no grazing fire.
7 Reference points (target numbers) within the sector of fire (7A thru 7F).
8 Magnetic north.

AMMUNITION
WARNING
This is the only ammunitJon authorized for use in your machine gun. If it is not shown, it
is not authorized.

CARE, HANDLING, AND PRESERVATION.
a. Do not open ammunition containers until the ammunition is to be used. Ammunition
removed from the airtight containers, particularly in damp climates, is likely to corrode.
b. Protect ammunition from mud, dirt, and water. If the ammunition gets wet or dirty , wipe it off
prior to use. Wipe off light con'osion as soon as it is discovered. Heavily corroded cartridges or
cartridges which have dented cases or loose projectiles should not be fired.
c. Do not expose ammunition to the direct rays of the sun. If the powder is hot, excessive
pressure may be developed when the gun is fired.
d. Do not oil or grease ammunition. Dust and other abrasives collecting on oiled or greased
ammunition will damage the operating parts of the gun, and oil on cartridges will produce
excessive chamber pressure.
